Automatic singularity avoidance using joint variations in robot task modification

Abstract

The research community has addressed the need to improve the flexibility of robot systems. Two particular concepts that have resulted from this research are off-line programming and modular tooling. These concepts are directed at allowing the robot system to be used to perform a variety of tasks with minimal setup time and to allow easy replication of an application. Both of these concepts require that the robot system have the ability to measure the position and orientation of features in the workspace. These measurements can then be used to perform coordinate transformations on each of the task data points. These modified task data points then, theoretically, facilitate the performance of the task by the robot system without human intervention.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
